The THL 3WI(SM) series is a family of compact 3 W dc/dc-converters with 4:1 input
voltage ranges. The product is available in SMD- or DIP-package. The internal filter
which meets EN55022 Class A without external components makes the converter
easy to design in.
They come with remote On/Off and short circuit protection. THL 3WI(SM) converter
is an excellent solution for data- and telecom applications and for instrumentation
and Industrial electronics.
